At present, there are many types of batteries, and the same battery also has different types. We know that cylindrical and square lithium iron phosphate batteries have been widely used recently, and they are mainly concentrated in the field of solar lights. Today, the editor will take you to understand the characteristics of their application.
Disadvantages of nickel-hydrogen batteries in the application of solar street lights:
1. Short life. The life of nickel-hydrogen batteries in the field of solar energy is only 1-2 years;
2. The charging voltage and charging efficiency are greatly affected by temperature. There is no wide-temperature nickel-hydrogen battery that takes into account high and low temperatures. With the temperature changes in the four seasons, the charging voltage of the nickel-hydrogen battery will fluctuate greatly. If the charging circuit cannot be well matched, it will cause low charging efficiency and safety risks.
Comparison of the advantages and disadvantages of cylindrical and square lithium iron phosphate batteries in solar street light applications:
1. Cylindrical energy storage lithium iron phosphate batteries can add PTC inside the battery cap, which can protect itself in the event of short circuit, high temperature, high current and other faults. When the fault is removed, the battery automatically resumes work. Due to different production processes, cylindrical power and square lithium iron phosphate batteries cannot add PTC protection inside the battery, and their safety is relatively poor.
2. When cylindrical energy storage lithium iron phosphate batteries are PACKed, there are gaps between the batteries, which is conducive to heat dissipation, and the shape of the PACK process is easy to control. The square lithium iron phosphate battery has relatively poor heat dissipation and shape arrangement flexibility.
The above is an analysis of the characteristics of cylindrical and square lithium iron phosphate batteries in solar street light applications. Each has its own advantages and disadvantages. The specific choice should be based on the specific actual situation.
